[Samba] samba4 bind9_dlz and dhcp

[L.P.H. van Belle]

Hai, 
 
A bit off topic in the samba forum, but i thinks this is the best place to ask. 
 
Im having some troubles to get the dhcp server fully working with samba4. 
I dont think this is a samba problem, but as i did say here maybe the best placy to ask.. 
 
It works, but not totaly. The strange thing is for example. 
 
My debian client is now working.  It adds and deletes as it should.  No problems at all. 
the only thing is see for the linux client, with dhcp server started in debug mode is this message: 
 
host: '.internal.domain.tld' is not a legal name (empty label)
 
( the full part ) 
DHCPACK on 192.168.1.50 to 00:19:d1:01:db:ea (rtd-ptr) via eth0
Release: IP: 192.168.1.50 HostName: rtd-ptr
execute_statement argv[0] = /etc/dhcp/bin/dhcp-dyndns.sh
execute_statement argv[1] = delete
execute_statement argv[2] = 192.168.1.50
execute_statement argv[3] = rtd-ptr
host: '.rotterdam.bazuin.nl' is not a legal name (empty label)
DHCP-DNS Update succeeded
DHCPRELEASE of 192.168.1.50 from 00:19:d1:01:db:ea (rtd-ptr) via eth0 (found)

At first the deleting part didnt work, after the modding of the script i got this works ok now.  ( base on hostname ) 
( Rowland, i'll send you the modded scripts as test i used your defaults. ) 
 
Now im testing the windows 7 clients. 
The add  of the A and TXT and PTR records are ok, works fine no problems.. 
 
But when turning the computer off, nothing, i dont see anything happing on the dhcp server. 
Im i hunting ghosts... ?? what im i missing... nothing is deleted, normal behaivor? 
Any enlightment would be great ! 
 
Greetz,

This is the part i have in the DHCP server within the subnet.
